Sentinel-3 SLSTR composites

This service takes as input a Sentinel-3 SLSTR Level 1 (SL_1_RBT___) product on DESCENDING orbit and uses the bands S3, S2, S1 to do a False Colour Infrared RGB composite. The output of the service is a EO data product in GeoTIFF format. The product is a RGBA GeoTiff file obtained through the composition of S3, S2, S1 bands [1]. The output GeoTiff is displayed in geobrowser with the possibility to access product metadata.
